4. Ocular Surface Disease Index (OSDI) score ≥13 at Visit 1 and Visit 2.
5. Total corneal fluorescein staining score (tCFS) ≥2 in either eye and ≥1 in at least one region at Visit 1 and Visit 2.

2. Severe: ≥2 quadrants of corneal damage and/or ≥30 corneal fluorescence staining spots on slit lamp microscopy.
Exclusion Criteria:
1. Subjects with severe dry eye requiring surgical treatment.
2. Systemic use of retinoids within the 12 months prior to Visit 1.
3. Subjects who have had intraocular surgery within 12 months prior to Visit 1 or who require intraocular surgery during the study; or subjects who have had eyelid surgery within 6 months prior to Visit 1.
